I can totally see Hagrid trying to bloody PET one before it zapped him or something! :P In my head, Barty Crouch Jr. was the Doctor under the Imperius curse (maybe after using the chameleon arch?) so the Daleks could totally have followed him. Chaos ensues!
as opposed to normal people who get married, have a baby, watch people grow up, meet baby's bf, see baby engaged and married and live long enough to spoil grandkids. Again, only in Doctor who does this happen
